Various fixes and promotion of warnings to real errors.

I didn't add Fixes: tags as digging up the original changes would be
cumbersome as the code moved a lot over the years.
Backporting this doesn't make sense anyways.

This series seems reasonable. I did a build of usr/ on arm64 and x86_64
allmodconfig, which showed no issues. I will give Nicolas a few days to
comment, after which I will apply these to the Kbuild tree so we can
start soak testing in -next.

Cheers,
Nathan

thanks.  With the exception of the already canceled patch 2, this looks
good to me.
